Description
The 9mm XWA is for the observer serious about wide-field deep-sky observing who has a mount that can handle the weight. It’s heavier than alternatives, yes but that weight buys you the largest exit pupil in the line short of the 20mm, and optics that maintain sharpness across 100 even at 133x. If your mount is rated for 500g or more in the focuser, and you care about seeing galaxies whole and faint nebulae in their full extent, this eyepiece belongs in your collection. The weight is a real consideration, but for the right observer on the right mount, it’s invisible compared to what the optics deliver.
